System for configuring an aircraft in a single-pilot mode or a two-pilot mode

1. A configuration system arranged to configure an aircraft in a mode selected from a plurality of modes including a single-pilot mode, in which the aircraft can be piloted by a single pilot on board or by a single pilot on board supplemented by a ground pilot, and a two-pilot mode, in which the aircraft must be piloted by two pilots on board, the configuration system comprising:

acquisition means and authentication means arranged respectively to acquire and then authenticate a configuration order that defines the selected mode and controls the configuration system to configure the aircraft in the selected mode;

first activation means arranged to activate equipment dedicated to piloting by a single-pilot on board when the aircraft is configured in single-pilot mode, and to deactivate dedicated equipment when the aircraft is configured in two-pilot mode; and

verification means arranged to, when the aircraft is configured in the single-pilot mode, verify that single-pilot flight conditions are met and inform the sole pilot on board and a ground station of the results of these checks, the single-pilot flight conditions including an operational state of the equipment dedicated to piloting by a single pilot on board.

2. The configuration system according to claim 1 , the configuration system also comprising second activation means arranged to prevent engine starting when the aircraft is configured in the single-pilot mode and all single-pilot flight conditions are not met.

3. The configuration system according to claim 1 , wherein the single-pilot flight conditions also comprise an operational state of a data link from the aircraft to the ground station, and a validation by the ground station of the selection of the single-pilot mode.

4. The configuration system according to claim 3 , wherein the single-pilot flight conditions also include confirmation that a flight plan programmed in the aircraft corresponds to a flight plan in the possession of a ground supervisor.

5. The configuration system according to claim 1 , wherein the authentication means is arranged to identify an author of the configuration order.

6. The configuration system according to claim 5 , wherein the authentication means comprise a reader arranged to read an identification hardware support in the possession of the author of the configuration order and/or a password entered by the author of the configuration order and/or biometric data of the author of the configuration order.

7. The configuration system according to claim 6 , wherein the authentication means includes communication means arranged to establish a connection with a ground server to perform the authentication.

8. The configuration system according to claim 5 , wherein the authentication means are arranged to identify a maintenance technician who issues the configuration order during a maintenance phase in which the aircraft is on the ground and the aircraft engines are switched off.

9. The configuration system according to claim 5 , wherein the authentication means are arranged to identify the pilot(s) on board.

10. The configuration system according to claim 9 , wherein the configuration system is arranged to configure the aircraft in the two-pilot mode when the configuration system acquires a first configuration order produced by a first pilot on board and defining the two-pilot mode as the selected mode, and a second configuration order produced by a second pilot on board and defining the two-pilot mode as the selected mode.

11. The configuration system according to claim 1 , comprising a virtual co-pilot arranged to load into an aircraft computer or computers a first software when the configuration system configures the aircraft in single-pilot mode, and a second software when the configuration system configures the aircraft in two-pilot mode.

12. An aircraft comprising original systems, integrated into the aircraft at the time of its manufacture and arranged to allow the aircraft to be flown by two pilots on board, the aircraft further comprising equipment dedicated to piloting by a single-pilot on board, and a configuration system according to claim 1 , wherein the dedicated equipment and the configuration system being introduced into the aircraft after its manufacture.

13. A method of converting a pre-existing aircraft originally arranged to be piloted by two pilots on board, comprising the steps of:

integrating into the pre-existing aircraft dedicated equipment for single-pilot flight; and

integrating into the aircraft a configuration system according to claim 1 .

14. The conversion method according to claim 13 , the pre-existing aircraft having original systems including a flight control system including pilot positioned in the cockpit, the dedicated equipment including a flight control device and an interface device for connecting the flight control device and the pilot controls to the original systems, the conversion method including the steps of:

when the aircraft is to be configured in the single-pilot mode, using the interface device to connect the pilot controls and the flight control device to the original systems; and

when the aircraft is to be configured in the two-pilot mode, replacing in the aircraft the first equipment of the interface device with second equipment that statically connects the pilot controls to the original systems.
